    Short Description

    ParallelMerge gathers data records from multiple CloverDX Cluster workers. The algorithm of the component is derived from the regular Merge component.

    Metadata

    ParallelMerge propagates metadata in both directions. The component does not change metadata priorities.

    The component has no metadata template.

    The component does not require any specific metadata fields on its ports.

    ParallelMerge Attributes

    ParallelMerge has same attributes as Merge. See Merge Attributes.

    Details

    ParallelMerge gathers data records from multiple CloverDX Cluster workers.

    The algorithm of this component is derived from the regular Merge component. For more details about attributes and other component specific behavior, see the Merge component.

    This component belongs to a group of Cluster components that allows the change from a multiple-workers allocation to a single-worker allocation. So the allocation of the component preceding the ParallelMerge component can provide multiple workers. The allocation of the component following the ParallelMerge component has to provide a single worker.

    [Note]Note

    For more information about this component, see Chapter 42, Data Partitioning in Cluster.
